    Question

    The price of a bottle is first increased by 15% and later the price was decreased by 24% due to reduction in sales. Find the net percentage change in the final price of the bottle. 

    A.

    Decrease of 13.9%

    B.

    Decrease of 12.6%

    C.

    Increase of 13.9%

    D.

    Increase of 12.6%

    Correct option is B

    Let the initial price be Rs. 100

    Firstly, the price was increased by 15%

    New Price = 15% of 100 + 100 = 15 + 100 = Rs. 115

    then reduced by 24%

    Final Price = 115- 24% of 115 = Rs. 87.4

    Net Percentage change = 10087.4100×100=12.6%\frac{100-87.4}{100}×100= 12.6 {\%}​​
